Subjects of this Section:
Manual target acquisition on the EPA radar
Semi-automatic plotting on the EPA radar
Differences between the EPA radar and the ARPA radar
The EPA radar differs from the ARPA radar principally in the fact that, on the EPA radar, targets have to
be acquired manually and can only be plotted semi-automatically. Furthermore, on the EPA radar, no
targets can be defined as references for reference target tracking.
8.1 Manual Target Acquisition and Semi-Automatic Plotting
On the EPA radar, up to 50 targets can be acquired manually and tracked semi-automatically.
In the case of manual target acquisition, the presumed target video is marked, and as a result it is
initially provided with the dotted square .
For semi-automatic target tracking, the same target is marked manually with the second plot several
minutes later at its new position. The radar now computes the speed vector of the target and displays
that vector (if this function is selected - see page 34). The first plot is now displayed as the past position
plot. The target symbol

changes. It moves along with the target on the computed course at the
computed speed.
The plotting must be repeated if the target symbol does not coincide with the target video, but not later
than within 15 minutes. After 10 minutes in each case, the operator is reminded by the PLOT xx NO
UPDATE alarm that a new plot should be set. If the next plot is not then performed within five minutes,
the plot is aborted and the alarm PLOT XX ABORTED appears.
Beginning the Manual Plotting
1. Click on the ACQ TGT (= Acquire Target) button; the button
flashes.
2. Acquire the target video by clicking. For as long as the ACQ
TGT button is flashing, more targets can be acquired in the
same way.
3. The acquisition function of the cursor is switched off by clicking into the PPI by means of the MORE
key or (with the DO key) by clicking again on the ACQ TGT area.

The same symbols are used as with the ARPA radar - see page 67.
